HCSA BINDER is a hydraulic binder based on calcium sulphoaluminate, rather than calcium aluminates which are the basis of CALCIUM ALUMINATE CEMENT or calcium silicates which are the basis of PORTLAND CEMENT. The difference gives HCSA BINDER properties particularly suited to formulators of products such as self-leveling or self-smoothing compounds, rapid hardening screeds, tile adhesives, non-shrink grouts, rapid setting and special mortars.
